IPC: H03M1/68
Abstract: 1,051,780. Electric selective signalling. GENERAL PRECISION Inc. Dec. 4, 1964 [Dec. 19, 1963], No. 49402/64. Heading G4H. A binary digital input corresponding to an angle # is converted into a sinusoidal function of the angle by coarse and fine weighted resistor networks, there also being a correction resistor network controlled via gates for adjusting the sinusoid from the coarse network when more than one resistor is connected into the latter. an attenuation resistor network controlled via gates for adjusting the sinusoid from the fine network, and logic and switch means controlled by the digital input to select the phase of A.C. power fed to the networks in accordance with the quadrant of the angle, that supplied to the correction network being 180 degrees out of phase with that supplied to the other networks. In Fig. 12b (not shown), the digital input stored in a register controls transistor switches for inserting. resistors in the coarse network 11, 225, 45, 90, the correction network 33, 56, 67, 78, the attenuation network Op to 78p. and the fine network 22 to 26. This arrangement provides a sin # voltage. The inverse outputs of the register stages control a similar cos 0 arrangement which differs in having an extra. resistor permanently connected into the coarse network to add one in the least significant digit position of the coarse network. The sin and cos voltages are fed to a transformer arrangement (Fig. 16. not shown) to produce cos #, cos (# - 120 degrees), cos (0+120 degrees) voltages on three lines, thus simulating a synchro. The two highest order bits of the digital input select one of two phases differing by 180 degrees for the power supply to the coarse, fine and attenuation resistor networks and a phase 180 degrees out of phase with this for the correction network (Fig. 15. not shown).

Abstract: 1,238,103. Intercommunication systems. INTERNATIONAL STANDARD ELECTRIC CORP. 5 June, 1969 [7 June, 1968], No .28431/69. Heading H4K. A telecommunication system includes a plurality of sub-stations connected to a common multiconductor which carries on one line a general A.C. selection signal applied to two changeover contacts through two oppositely poled rectifiers so that the A.C. signal can be selectively applied to two other lines by operation of the contacts wherein this signal causes an evaluation unit to operate a connecting unit to connect the sub-station to the speech lines. The changeover contacts, rectifiers evaluation and connection units are housed at the sub-station. As shown an audio frequency general selection signal is applied via line 1 to the connection between rectifiers Gl5<SP>1</SP>, Gl6<SP>1</SP> in each sub-station and a halfwave A.C. signal selectively transmitted on lines 2, 3 by operation of one of keys T1<SP>1</SP>-T4<SP>1 </SP>. Receiving rectifiers Gl1<SP>1</SP>-Gl4<SP>1</SP> are connected to evaluating units W1<SP>1</SP>, W2<SP>1</SP> in any desired combination so that each sub-station responds to its own pattern of transmitted A.C. signals. An enabling line F1<SP>1</SP> connects units W1<SP>1</SP>, W2<SP>1</SP> so that when W1<SP>1</SP> responds it enables W2<SP>1</SP> so that it can receive a second signal within a fixed time. On receipt of a signal, connecting unit B<SP>1</SP> is operated to connect the transmission device Ue<SP>1</SP> to the line through contacts a<SP>1</SP>, b<SP>1</SP>. More than two digits may be used for selection and the number of evaluating units is increased accordingly, alternatively a further four changeover contacts may be provided transmitting on to lines 4, 5 of the multiconductor. Group and collective call facilities can be obtained by the use of additional keys at the sub-stations. Multiple seizing of the multi-conductor lines can be prevented using known circuits. The evaluating and connection units can use either relays or electronic switches. In telemetering and like installations, some of the stations may be adapted only to be called.

Abstract: 1,251,732. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORP. 26 Sept., 1969 [11 Oct., 1968], No. 47506/69. Heading H1K. The device shown is an N-channel IGFET 16, 10, 18. Surrounding the transistor is an annular N+ guard region 20 of opposite conductivity type to the substrate 10. By maintaining a reverse bias between this guard region and the substrate leakage current due to inversion is prevented. Instead of the connection shown between guard region 20 and source 16, the guard region may be held at a positive potential, this possibly being higher than the drain potential. In an integrated circuit guard regions may surround individual transistors or groups of transistors. Though described as annular, guard regions need not completely surround the transistor(s). In general the body may be of silicon; source drain and guard regions may be formed by diffusion or by etching and epitaxial filling; the insulation may be of silicon oxide, silicon nitride, or alumina; and the electrodes may be of aluminium or platinum silicide.

Abstract: 1,259,395. Radar. BRITISH IRON & STEEL RESEARCH ASSOCIATION. 13 Feb., 1970 [14 Feb., 1969], No. 8126/69. Heading H4D. The distance between a datum point and a surface is measured by transmitting a signal compounded from two microwave signals having a predetermined frequency difference from the datum point to the surface, receiving a reflected signal from the surface, and measuring the phase difference between the transmitted and received difference frequency component of the compounded signal. The level of a liquid or solid load in a hopper or the thickness of a steel billet placed on a reference surface may be measured. As shown in Fig. 2, two microwave generators 30, 31 generate microwave signals # 10 GHz with a known frequency difference in the range 10 MHz to 150 MHz maintained by a phaselock loop (not shown). The generators 30, 31 are connected to a magic T 35 through isolators 32, 33 and one or two level-set attenuators 34. A reference difference frequency signal is detected at 38. The received reflected signal is channelled through directional coupler 40 to a detector 41. Both detected signals are then fed to a phasemeter 42. Preferably the detected signals are mixed with another frequency so that the phase measurement can be made at a lower frequency (# 1 MHz). The 1 MHz signals may be further heterodyned to produce signals at 150 kHz. The phase-lock loop may operate at the 1 MHz frequency (Fig. 3, not shown). In this arrangement, the range may be changed by altering the frequency of oscillator (51) so that the wavelength of the difference signal may be set initially large for search purposes and then progressively reduced for increased accuracy.
